Mutual Construction Company (TVL) (Pty) Ltd v Komati Dam Joint Venture

The appellant hired to the respondent a self-propelled articulated dump truck together with its operator for use on a dam construction site. Although the operator remained the general employee of the appellant, the contract provided that while on site the operator would work under the sole and absolute control and supervision of the respondent. While driving on the site, the operator fell asleep, causing the truck to leave the road and collide with an embankment, resulting in extensive damage. The appellant sued the respondent for repair costs and loss of income. The High Court accepted that the operator was negligent but held that fairness and policy considerations meant the respondent should not be liable, and dismissed the claim.

The appeal succeeded with costs. The High Court’s order was set aside and replaced with an order directing the respondent to pay damages to the appellant in an amount agreed or proved, and to pay the costs of the proceedings determining liability.

The case is an important authority on the contractual allocation of risk and liability in hire agreements involving plant supplied with an operator. It clarifies that liability in such cases depends on contractual construction rather than delictual vicarious liability, and that an operator supplied with hired equipment may, by agreement, be treated as a functionary of the hirer for purposes of risk and negligence.
